Low side with high pressure and High side with 150psi
Low side with high pressure and High side with 150psi
Car is a 2009 volvo s40 rurbo. ac compressor cycles on and off. Stays on for about 5 seconds and shuts off for about 15 seconds and repeats. When I hook the manifold gauges up while car is off, the low side was over 300psi and the high side was around 150psi. Then I start the car and turn the ac on. The low side drops to about 100psi and the high side shoots up to over 400psi. then the safety switch kicks on and shuts the compressor off. then this basically jist repeats. What could it be? Thank. Car is an 2009 volvo s40 turbo. thank you.
